Set output AVC (H.264) encoding profile. The older the target device, the "lower" profile you should set. More info can be found on the wiki.
Set output AVC (H.264) profile level. Leaving this setting in "Auto" will calculate the correct level and is the best choice in most cases. More info can be found on the wiki.
CRF (Constant Rate Factor) defines a constant compression ratio ensuring that every frame gets the number of bits needed to achieve a certain visual quality.

mov

MOV is a multimedia container format developed by Apple Inc. and introduced in December 1991 with the launch of the QuickTime multimedia framework. As the native format of QuickTime, MOV pioneered many concepts that later influenced the ISO base media file format (MPEG-4 Part 12) and its derivatives, including MP4. The container uses a hierarchical atom (or box) structure where each atom holds specific types of data — from video and audio tracks to metadata, text, and timecode information. MOV supports an extremely broad range of codecs including H.264, HEVC, ProRes, Apple Intermediate Codec, AAC, and PCM, among many others. This codec flexibility, combined with features like multiple track support, reference movies, and edit lists, has made MOV a staple of professional video production. The ProRes codec from Apple, commonly delivered in MOV containers, is an industry standard for post-production and broadcast finishing. The format handles both compressed delivery-quality content and high-bit-rate production-quality footage with equal capability. Precise timecode and metadata handling make MOV particularly valued in workflows requiring frame-accurate editing and reliable exchange between production tools. MOV is natively supported across all Apple platforms and widely recognized by professional editing software on all operating systems, maintaining its relevance across decades of evolving video technology.

f4v

F4V is a multimedia container format developed by Adobe Systems as an evolution of the Flash Video ecosystem. Introduced in December 2007 with Flash Player 9 Update 3, F4V is based on the ISO base media file format (MPEG-4 Part 14) and was created to support the H.264 video codec and AAC audio within the Adobe Flash platform. Unlike its predecessor FLV, which used a proprietary container structure, F4V adopts the standardized MP4-compatible atom/box architecture, making it more interoperable with other media tools and workflows. The format supports advanced features including high-profile H.264 encoding, multichannel AAC audio, and timed text for subtitles and captions. F4V represented a strategic move to address the growing demand for H.264 content on the web, as the older FLV container could not efficiently package this newer codec. During its peak years, F4V powered much of the high-quality video content delivered through Flash-based streaming platforms and video players on the web. The container supports both progressive download and dynamic streaming delivery, offering content publishers flexible distribution options. While the decline of Flash Player in favor of HTML5 video has reduced the creation of new F4V content, the MP4-based structure means the contained media streams are readily accessible through modern tools.

Frequently Asked Questions

Why convert MOV to F4V?

F4V is Adobe Flash Video based on the MP4 container. Some legacy media servers and content systems still require F4V for their video delivery pipelines.

What plays F4V files?

VLC, PotPlayer, Adobe Flash Player (archived), and media players that support MP4-based containers. F4V uses standard H.264 video encoding internally.

Is F4V different from FLV?

Yes — F4V is based on the ISO MP4 container and uses H.264 video. Older FLV uses its own container with VP6 or Sorenson codecs. F4V is the newer variant.

Does F4V support HD?

F4V handles HD content through H.264 encoding. Full HD and even higher resolutions are supported within the format specification.

Is F4V still relevant?

While Flash has been retired, F4V files persist in archives and some enterprise systems. The H.264 core means they remain playable in most media players.
